To CLZZ whom may concern: I

Be it known that I, HERMANN HENSCHEL, manufacturer, of Luckenwalde, inthe Kingdom of Prussia and German Empire, haveinvented a new and usefulPaper-Box-Nlaking Machine, of which the following is a specification,reference being had therein to the accompanyin g drawings.

This invention has been patented to me by British Letters Patent No.13,415 of October 4, 1887, and German Patent No. 40,405, of J anuary 27,1887.

The object of my invention is to provide mechanism which will form a boxat one operation, said box having when inished a projecting bead aroundits lower, edge and plain cylindrical sides extending therefrom to theupper edge.

In the drawings, Figure l is a vertical section through thecutting-plunger, the male die carried therein being shown in sideelevation, and the female die and support therefor, together with theblank, being also in seetion, all the parts being in normal positionready to begin the operation of forming the box. Fig. 2 shows thecutting-plunger and the male die moved downwardly a part of their entirestroke, the blank at this period of the operation having been out andpressed into cylindrical form. Fig. 3 shows the plunger and die at thelimit of their downward movement, the box having now been forced throughthe female die, so that its lower edge Fig. 4 shows the next -step inthe operation, the outtin g-plun ger and both the male and female dieshaving risen together, the relation between these parts being maintainedas in Fig. 3, and this figure .also shows in section the block whichcauses the formation of the rib or bead on the box when the plunger anddie descend. Fig. 5 shows this action of forming the bead by the descentof the female die and cutting-plunger. Figs. G and 7 are similar viewsrepresenting the box as completed and being discharged.

The female die B B, having an opening b, of oval or .round shape, isheld by long screws C C, projecting from the supports A A. The

- nuts D D on the upper end of the screws are somewhat above thefemaledie, so as to al low the same to be moved to and fromthe bars AA, for apurpose hereinafter stated. This die B supports the blank, as at o, Fig.l, and directly above the opening in the die 4and over the blank thecutting-plunger E is about the male-die seat forms a cutter f, whichsevers the blank to the proper size when said edge is passing the upperedge of the femaledie opening. The male die projects below thecutting-edge, and of course is smaller in diameter than the opening inthe female die, and thus when the said die with the cuttingplungerdescends it forces the blank into the female die. and thus forms thecylindrical box, the sides of the same being between the sides of thesaid dies, as in Fig. 2, and at the same time this action takes placethe cutting-plunger moves downwardly, and at the time the box has beenformed, as in Fig. 2, the cutting-edge f has trimmed the surplusmaterial from the edge of the blank, as at t, Fig.' 2. The male die E3is movable to and from its seat in the cutting-plunger', and in theoperation of the parts thus far described it occupies its lowest oroutward position in relation thereto, bearing iirmly against thebox-bottom; but at the proper time, as will hereinafter be pointed out,the said die moves back into its seat and leaves the bottom of the boxfree from support for the purpose of allowing the same to be upset toform the beadf After the box has been formed, as in Fig. 2, the male dieand plunger continue their movement until thelower edge of the box haspassed below the lower edge of the female die. This limit of movement isshown in Fig. 3, and after this has been reached these three parts-viz.,the cutting-plunger,

male die, and female die-rise, but keep in the 9 same position relativeto each other. A plate or anvil K is then moved into the opening in thevsupport A A to fill the same, and this is shown in Fig. Il. -The maledie now moves back in its seat, leaving the bottom of IOO the boxwithout interior support, and upon the downward movement of the cutterand female die, which new occurs, the bottom of the box is upset and abead is formed between the anvil or plate K and the felnale die B, asshown in Fig. 5. After this the anvil K is removed and the continuedmovement of the plunger and die E3 effects the discharge of the box, asin Figs. 6 and 7, the latter of which shows the cuttin g-plun ger andmale die raised again. The waste material i is then removed.

For the purpose of operating the male die to change its position inrelation to the eutting-plunger, as above described, I employ a wedgeE2, which works through an opening in the said plunger and the shank Eof the male die.

I claim as my inventionl. In combination, the female die having a plaincylindrical opening extending through it to a point at or near its uppersurface, the cutting-plunger E', having cutting-edges to pass into theopening in said die and cut a blank from the body of the material whenit reaches said upper surface of the die, and a male die E3, carried bythe plunger projecting at all times beyond the cutting-edgef, wherebythe body of the material will first be pressed to form the box by themale die and then eut by -the edge f, substantially as described.

2. In combination, the female die B, the cutting-plunger E, the male dieprojecting normally beyond the cutting-edge of said plunger and arrangedmovably in said plunger, the Said female die being movable, means forcontrolling the male die, and an anvil or plate K, substantially asdescribed.

3. In combination, the female die having an opening therethrough, meansfor cutting and forming the blank and for forcing the same partiallythrough the female die, so that its lower edge will project therefrom,and the anvil or plate K, adapted in size to afford a bearing for theprojecting edge of the box, the said female die and anvil K beingmovable, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

HERMANN HENSCHEL.
